Issue with Kidani is that the two wings, north and south, are extremely long: end rooms of north wing are about 1/3 mile from the lobby, south wing just over 1/4 mile. Thus many request close to lobby or close to community hall (which is right near the lobby). Also many prefer the lower floor (2 or 3) direct sight view of animals rather than the more panoramic upper floor (4 and 5) view of the savanna and thus request lower floor. I have usually gotten my requests like those requests when I made them but for the last time I went earlier this month, I had requested close to lobby and low floor and got 4th floor right near the end of the south wing, i.e., neither request was even close to being met met.
Other possible requests to consider: (a) close to the Rafiki elevator; that puts you a little ways from the lobby on the north wing but gives you the shortest possible walk at the resort to the pool, from that elevator on the ground floor (the ground floor is the parking garage); (b) close to the Timon elevator; puts you a little ways from the lobby on the south wing but fairly close to the exit on the south wing that is nearest the bus stop; (c) if you want to be close to Jambo, request room near the Zazu elevator, the last elevator on the south wing; if you request close to Jambo, you could get a room on the south wing that is well past that elevator but you have to go back to that elevator to get to the ground floor and walk to Jambo. The walk to Jambo is little more than 1/4 mile from the Zazu elevator.
Also, you likely want to request Sunset savanna view (the largest savanna) because it has giraffes and Pembe does not. Any request that automatically puts you near lobby or on the south wing (near community hall, near Timon elevator, or near Zazu elevator) does not really need a Sunset savanna request because all savanna rooms in those areas face only Sunset.
